FERDINAND JOSEPH ZOPPEL, OF CINCINNATI, OHIO.

CONDENSER.

Application filed December 13, 1919. Serial No. 844,595.

T 0 allan/1,0m t 'may concern 4 Be it known that I, FERDINAND JOSEPH Zor- PEL, a citizen of the Republic of Austria, residing at Cincinnati,. in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Condensers. of which the following is a specification.

My invention relates to refrigeratingapparatus and particularly to the part known as the condenser, and to its connective relation with other parts of the general system in which it is employed; being, in effect, an improved construction of the condenser in which is embodied an oilseparating chamber and devices for oil separation. cognate object, also, is to produce a construction at once simple and compact, with a View, (1), to construction and arrangement of parts, facilitating access to all requiring manipulation in construction and use; (2), to the elimination of all avoidable jointings or connection of parts requiring packings and thereby possibilities of leakage; and (3) a structural arrangement enabling the assembly of the condenser with other integral parts in a complete refrigerating apparatus at once compact in use, low cost of production, and greater eiiiciency in use.

With these general purposes certain minor features of advantage are combined, as will further appear.

My invention is illustrated, in its preferred form, in the accompanying drawings forming part of the specification following,-the several parts mentioned being designated by letters of reference.

Figure 1 is an elevation in axial cross section of the condenser and immediately associated connections; and

Fig. 2 a perspective elevation of the bailleplate employed in the oil separation.

Referring now to the drawing herewith,- in which the several parts are designated by digital numbers,--1, designates a hollow cylinder constituting the condensing chamber, closed at the top except as hereinafter specified and closed at the bottom by its seating upon the liquid-ammonia receiver, 2, of suitable form; and held tight by bolting through a bottom flange, 3, in conne:- tion with ordinary gaskets. Extending axially above and as art of the normal top of the condenser, 1, 1s a short cylinder, 4, of

reduced diameter, closed at the top by a removable cover plate 5 from which depends a baille-plate, 6, within the cylinder, 4.

The cylinder, 4, is extended, with slightly increased diameter, downward Within and to near the bottom of the cylinder, 1; and has a closed bottom, thus forming a receptacle for oil separated by the baffle-plate, 6.

The annular space within cylinder, 1,surrounding the lower extension of the cylinder, 4, is occupied by the pipe coil, 7, whose receiving and discharge terminals, 8 and 9, respectively, extend through the top and bottom of the chamber.

The upper or receiving pipe-terminal, 8, connects as follows: A delivery pipe, 10, enters the side of the small cylinder, 4, facing the baiiie-plate, 6. On the opposite side of` the baiiie and in line with the pipe 10 is a discharge pipe 11 which is connected by an elbow-union, 12, with the intake pipe-terminal, 8. The outgoing terminal, 9, is carried downward through a union 13, and stop-valve, 14, and extension-pipe, 15, into the liquid-ammonia receiver, 2.

The condenser-cylinder, 1, carries, near the bottom, the condenser-water inlet-port, 16; and, near the top, the condenser-water outlet-port, 17, to maintain the necessary circulation.

The ammoniaand oil-vapor enteringthrough the delivery ipe, 10, strikes directly against the baille-plate, 6, which has a p ane face with parallel corrugations extending vertically as indicated in Fig. 2.-

It approximates in width the internal diameter of the cylinder, 4, so that the gas and vapor are compelled to pass downwardly around the bottom of the baffle plate. The oil-vapor, being heavy, clings to the bailleplate and eventually drops into the bottom of the inner extension cylinder, 4.

Whenever desired, the oil can be withdrawn through a tube, 18, which extends from near the bottom of the cylinder-extension, 4, upward and outward through the cover plate, 5, stop-valve, 19, and discharge pipe, 20. Upon opening the stop-valve, 19, the pressure upon the oil level, will force the oil through the valve and outward through the connecting pipe, 20.

The ammonia vapors, freed from oil, pass under the baille-plate, 6, and out through the pipe, 11, and elbow, 12, into the coil, 7, of the condenser, from which it emerges in denser coil, 7, in

condensed form through the outlet-terminal connection, 9, of the coil into the liquid receiver, 2.

It will be understood that in the ordinary operation of the machine, the ammonia passes into the condenser under compression from a compressor (not shown) and by reduction of temperature and continued pressure isliquefied. The terminal, 9 of the conlpassing through the eXtension plate 21 of t e liquid ammonia receiver 2, is provided with screw nuts, 22, with 1ntervening packing gaskets; and the termlnal, 8, in passing through the top well of the condenser is provided with an ordinary screw stufling box 23 with packing askets.

I claim and desire to secure by etters Patent of the United States:

l. In condensing apparatus, a condensing chamber provided with an oil pocket having a closed bottom, said pocket embraced within and extending above the condensing chamber through an otherwise closed top, said chamber and pocket being formed as a single integral structure provided with a' lower flange adapting it t0 rest upon and be secured to the ammonia receiver as a bottom support and closure.

2. In a condenser apparatus of the character indicated, in combination with the condenser cylinder and its central pocket, a removable top or cover for said central pocket, having a baffle-plate integral therewith and extending downward within said pocket.

3. In a condenser apparatus of the character indicated, a separator-pocket located and arranged in the condenser-chamber as described, and having a pressure-actuated outlet leading from the bottom of the separator-pocket, through its cover plate.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

FERDINAND JOSEPH ZOPPEL.
